Re: Aztec Angler's Live Person
I think its definitely something to be kept on the site. It sets your site apart from others (until the fad truly hits) and gives information you want known without requiring the customer to click anywhere.
One alteration I would make is to make the intro spiel a bit shorter and follow it with something like "click on my hat/wherever to learn more", and then let the rest of the spiel carry on, after thanking them for the click. I make this recommendation because it will get viewed many times by folks in an office or cube farm, and a 2-4 sentence spiel will be less interruptive/conspicuous than a longer one.
